204 Calibrating and Verifying Performance
Chapter 4
CALibration:VOLTage?
CALibration:VOLTage? performs the voltage-related calibration procedures.
Calibrations performed are: Calculate A/D offset and gain for each VXI supply.
Externally measured voltages previously reported to the enhanced monitor through
CAL:VAL:VOLT are used for these calculations.
Returned Data
Comments
•
Make the calibration values measurements and provide them to the enhanced
monitor via the CAL:VAL:VOLT command immediately prior to using this
command. Old values will be used otherwise.
•
The calibration values (reported to the enhanced monitor with
CAL:VAL:VOLT) have default values that will be used by the calibration
routines if no values are ever measured and reported to the enhanced monitor.
See CAL:VAL:VOLT for details.
Error Conditions
The following table lists the most common error conditions and causes. Error
numbers and corresponding messages can be found using SYSTem:ERRor? query.
Reset Condition
Calibration is not affected by reset. However, if a *RST is issued while a calibration
is occurring the calibration will be aborted.
